H40.831
Aqueous misdirection, right eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Aqueous misdirection, also known as malignant glaucoma, is a rare eye condition that affects the flow of fluid within the eye. This disorder causes fluid to be misdirected, leading to increased intraocular pressure and forward displacement of the lens and iris. When it occurs in the right eye, it is specifically classified under the ICD-10 code H40.831. The condition can cause significant visual discomfort and requires prompt diagnosis and management to prevent lasting damage.
Causes & Symptoms
Clinical Causes: Previous eye surgery or procedures, especially glaucoma surgery Anomalies in the anatomy of the eye, such as a shallow anterior chamber Inflammatory conditions leading to blockage of fluid pathways Potentially idiopathic, meaning the exact cause is unknown in some cases Certain risk factors, including hyperopia (farsightedness) and age-related changes
Key Symptoms: Sudden or gradual decrease in vision Eye pain or discomfort Headache around the affected eye Nausea or vomiting in severe cases Notable swelling or redness of the eye Narrow or closed-angle glaucoma symptoms, such as halos around lights A visibly enlarged or tight eye upon examination
Diagnostic & Treatment
Diagnosis Path: When a healthcare provider suspects aqueous misdirection, they will perform a comprehensive eye examination, including measurements of intraocular pressure. Additional diagnostic tests may involve ultrasound biomicroscopy or gonioscopy to assess anterior chamber angles and anterior segment anatomy. Imaging techniques and detailed patient history help confirm the diagnosis and exclude other conditions with similar presentations.
Treatment Protocols: Treatment strategies aim to reduce intraocular pressure and address the underlying misdirection of fluid. Common approaches include:
